Q. Factor completely.\newline5x2+3x2 5 x^{2}+3 x-2 \newlineAnswer:
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is 5x2+3x25x^2 + 3x - 2. Here, the coefficient of x2x^2 (a)(a) is 55, the coefficient of xx (b)(b) is 33, and the constant term (c)(c) is 2-2.
  2. Find Multiplying Numbers: Find two numbers that multiply to acac (5×2=105 \times -2 = -10) and add up to bb (33).\newlineWe need to find two numbers that multiply together to give 10-10 and add up to 33. The numbers that satisfy these conditions are 55 and 2-2 because 5×2=105 \times -2 = -10 and 5+(2)=35 + (-2) = 3.
  3. Rewrite Middle Term: Rewrite the middle term using the two numbers found in Step 22.\newlineWe can express the middle term 3x3x as the sum of 5x5x and 2x-2x. So, the expression becomes 5x2+5x2x25x^2 + 5x - 2x - 2.
  4. Factor by Grouping: Factor by grouping.\newlineWe group the terms as follows: (5x2+5x)+(2x2)(5x^2 + 5x) + (-2x - 2). Now we factor out the common factors from each group. From the first group, we can factor out 5x5x, and from the second group, we can factor out 2-2.\newlineThis gives us: 5x(x+1)2(x+1)5x(x + 1) - 2(x + 1).
  5. Factor Common Binomial: Factor out the common binomial factor.\newlineWe notice that x+1x + 1 is a common factor in both terms. We can factor this out to get the final factored form: 5x25x - 2(x + 11\).
